Models and results of dynamic causal modeling (DCM) regarding the mirror neuron system (MNS). A. Analyzed brain regions rendered on the spatially normalized brain. V1 = Primary visual cortex; MTG = Middle temporal gyrus; IFG = Inferior frontal gyrus. B. Analyzed models. Thin arrows indicate intrinsic connections between brain regions. Bold arrows indicate the modulatory effects of dynamic presentation. C. Mean coupling parameters (± SE) for the control (CON) and autism spectrum disorders (ASD) groups. Statistical comparisons showed that all parameters were significantly weaker in the ASD than in the control group (t-test, p < .05).
